TPO12 reading <overshadow 的用法?> - 英檢

TRANSITION TO SOUND IN FILM (TPO12)

Paragraph 3：Beyond that, the triumph of recorded sound has overshadowed the
rich diversity of technological and aesthetic experiments with the
visual image that were going forward simultaneously in the 1920s.

不過我看黃金閱讀的翻譯是
[the triumph of recorded sound] 被 其它新技術掩蓋?
-->可是看了第七題的正確的答案後 我又覺得好像是 其它新技術 被聲音給掩蓋?
有人可以指點一下嗎?
我覺得好像怪怪的 不知道是不是被動式 (被掩蓋) 都要加上by? 如下面example


查了google字典 overshadow 的意思是: 使顯得遜色；使黯然失色

ex1:He had always been overshadowed by his elder sister.
^^^ A ^^^^^^^^ B
他與他姐姐相比總是相形見絀。 A被B比下去

ex2:The garden is overshadowed by tall trees.
^^^^^^^^^^ A ^^^^^^^^^ B
花園中大樹濃蔭密佈。 A被B掩蓋

節錄第七題
7. According to paragraph 3, which of the following is NOT true of the technological and
aesthetic experiments of the 1920's?
X Because the costs of introducing recorded sound were low, it was the only innovation that
was put to use inthe1920's.
○ The introduction of recorded sound prevented the development of other technological
innovations in the 1920's
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

○ The new technological and aesthetic developments of the 1920s included the use of color, new
screen formats, and television.
○ Many of the innovations developed in the 1920s were not widely introduced until as late as
the 1950's.
